7 Claims. 20-53) The present invention relates to a window constructionand refers more particularly to a window comprising a window frame andpane elements 'tiltably supported in said frame on substantiallyhorizontal axes extending laterally'of said frame.

s An object of the present invention is to provide a windowof the abovetype with Weatherstrip means. I

Another object is to provide means for tilting one or more of said paneelements, the means being operable by a single actuating lever or thelike and operative on said pane elements atboth ends of the latter, themeans further being operative to tilt pane element to which it isconnected by the same amount and at the same time.

. Yet another object is that,if, through abuse or other accident, thetilting means becomes damaged in such a way as tobe wholly inoperative,the pane elements will by gravity assume a vertical, closed position. I

A further object is to provide means associated with said tilting meansand actuated by the same actuating means for'actuating said Weatherstripmeans into sealing relation with said window frame after said paneelements have been actuated into substantially vertical and closedrelation, and for actuating saidweatherstrip means out of said sealingrelation previous to tilting said pane elements. 7

Another and further object is that the sealing action of saidWeatherstrip means shall oonstitute a lock means preventing relativemotion between said pane elements and said window frame.

Still another object of the invention is to provide a window frame inwhich the four elements constituting the sides of the rectangular frameshall be disconnectable from one form for convenience and economy inshipping.

Other objects will in part be obvious therefrom and in part will bepointed out as the description proceeds. I

window emfRefer-ring now in detail to the drawings, my im- 1 provedwindow [0 comprises thev substantially rectangular window frame IOA, thelatter comprising the side members I013; H,--header l2 and sill l 3, allpreferably of channel sheet met-a1 construction. The side members HlB,II have surfaces 13A, I3B finished square with their length, andportions projecting beyond said square finished portions and formed withslots I3D. The portions I30 project through slots 13E in header l2 andsill l3. Wedges I3F are'driven into slots 3D to draw the square finishedportions l3'A, |3B against the sill l3 to detachablyconnect the threesides together into the substantially rectangular window frame IDA. Theframe can thus be shipped completely knocked down at a considerablesaving of shipping space, and assembled on thejob.

The bars l4 tending longitudinally thereof, and bolts 14B extendingperpendicularly from side members IOB extend through slots I 4A andcarry the nuts M C. whereby the bars 14 are vertically slid-ably mountedin the side members HiB. Bars [4 are further formed with the slots MD,which are so located relative to one another as to constitute a rack l5.

A circular gear I6 is rotatably mounted on stud l! on side member IDEand is operatively connected to handle 18, and to bar Hi, the teeth ofgear I 6 engaging the rack l5,so that rotation of handle l8 rotates gearlb to slide bar l4 relative to side member 103.

.Bars [4 are formed with a plurality of long openings I9 and comprisethe racks 2!! along one side of the openings and facing thereinto.

The pane holding elements or sash 20A comprise at each end the side bars2013 having an elongated body of modified H cross section, the lattercomprising a bight or U-shaped portion 200 and a guide ledge portion 20Dextending in a common plane with and integral with one of the arms 20Eof the U portion 200.

Gears 2i engage the racks 2|] of bars M in the side members IBB, H, andare securely mounted on the .pivot shafts 22 of pane holding elements20A, the shafts 22 being journaled in the side members lllB, H at 22A.Firmly mounted on gears 2| are the parti-cylindrical segments 23 formingpart of the window locking and weatherstrip actuating mechanism 24 to bedescribed hereafter.

The window panes '25 are made up of two sheets of glass separated byspacer strips 25A. Straps 2-6 rotatably connect the pivot shafts 22 tothe other arms 26A of the U-shaped portions are formed with the slots"MA ex- 3 20C opposite the arms 28E in the plane of the guide ledge 20D.The .panes 25 are frictionally and resiliently held in the U-shapedportions 20C by the insulating material 21 located under compressionbetween panes 23 and portions 200.

The following means are provided for causing simultaneous and equalmotion in the same direction of the bars l4-mo-un'ted in each of theside members IOB of window frame MA.

A shaft 28 is rotatably jou-rnaled as at 23A in both side members 10B,I, extending therebetween inside the sill I3. Gears 29 keyed to shaft 28near each end thereof engage the racks 33 of bars l4, so that slidingactuation of the bar It illustrated in Figures 3, 4Vand 5 and on theleft of Figure 1 rotates shaft 28 and thus slidingly actuates thesimilar bar l4 nthe right of Figure 1 by the same amount in the samedirection at the same time. i The locking and weather strip mechanism 24previously mentioned comprises the sleeve bearing 3| and the sleeve 32slidably mounted on' pivot shaft 22 and in bearing 31. Segr'nent 23 isformed with the arcuate cam slot 33, and pin 34 mounted in sleeve 32extends radially therefrom and into slot' 3'3. The weath-erstrips 35, ofL cross section, are rigid and equal in length to the height of the paneelements 29A and are firmly mounted by means of their integral collars36 on the sleeves 32. Resilient insulating material 37 extends aroundthe foot of the L of weatherstrips 35 and in sliding contact with theguide ledge 26D. Thus sleeves 32 and weatherstrips 35 are slidable asunits longitudinally of pivot shafts 22 and pane elements 23A. Sinceouter surfaces of weather'strips 35, extending for a substantialdistance on both sides of the axis of pivot shafts 22 and of sleeve 32,are in sliding surface contact with the inner surfaces 20F of guideledge 23D, said surface 28F extending substantially longitud-inally ofpane holding elements orsash 23A, relative rotation between Weatherstripand sash is prevented, and rotation of sleeve 32 is effective torotatethe pane elements 23A. In the illustrated position of Figure 5,weatherstrips'35 ex tend into the Weatherstrip grooves 33 formed in'side members NIB, 1 l, and extending from header 2 to sill i3 and facinginto the window opening.

The window'operatesby rotating handle I8 clockwise of Figure 1, thusrotating gears H in the direction of the arrow of Fig-ure 3 andclockwise of Figure 4, sliding bars id upward, both bars [4 of thewindow moving together as previously explained. Upward movement of barsl4 causes rotation of gears 21 counterclockwise of Figure 3 and in thedirection of the arrow of Figure 4. Segments 23 being fast to gears 25will move with them. Pins 34 cannot rotate as they are fast to sleeve 32which are fast to weatherstrips 35 which are engaged in grooves '38.Therefore pins Stand sleeves 32 with them will be cammed to the right ofFigures 4 and, 5, disengaging weatherstrips 35 from grooves 38. Becausethe pivotal suspension of pane elements 28A is higher than the centerof. gravity thereof, and also be'-' cause the axis of rotation of thepane elements is located inwardly of the window relative to the centerof mass of the pane holding elements,

in all positions thereof, gravity will bias pane holding elements 23Atowards a substantially vertical, closed position, so that they are atall times resisting the tilted position illustrated in Figure 2. Pins 34being fixed against'rota'tion relative to pane elements 20A will thusresist rotation away from the vertical position of pane tion of handle[8 is first effective to progressively release pane holding elements 23Ato the action of gravity to close the same, after which further rotationof segments 23 will cam pins 34 to the left of Figures 4 and 5 to returnweatherstrips 35 into grooves 38' to simultaneously lock the window andseal it against the entry of the weather.

It will thus be seen that there is provided a device in which theseveral objects of this invention are achieved, and which is welladapted to meet the conditions of practical use. Asvarione possibleembodimentsw might be made of the above invention, and as. variouschanges might be made in the embodiments above set forth, it is to beunderstood that all matter herein set forth or shown in the accompanyingdrawing is.v to be interpreted as illustrative and not in a limitingsense. 7 3
